Abstract: FAST FRAME RATE SENSOR READOUT   ABSTRACT OF THE DISCLOSURE Prior art electronic cameras that use solid state area image sensors are generally limited to operation at frame rates less than about 120 frames per second.  Such frames rates are limited, principally, by the maximum data rate at which solid state sensors may be operated.  In a preferred embodiment wherein photosights of a sensor are arranged in rows and columns, the sensor is read out in "blocks" of photosite, with each block being comprised of a plurality of adjacent photosite rows. A block of photosites is enable by the application of an enablement signal to the photosites within the block; and a column address signal is sequentially applied to the photosite columns to effect column-wise readout of the photosite rows within the enabled block.  The output signal so produced is, therefore, comprised of block information in a "serial" format, while the information content of each block is comprised of a plurality of line signals in a "parallel" format, such line signals corresponding to the individual photosite rows within that block.

Abstract: LOAD OUT PIVOTING CHUTE SYSTEM Abstract of the Disclosure A load out chute system for controlling and directing the flow of relatively large quantities of bulk material, such as coal, is disclosed.  The chute system includes an upper chute defining an upper flow path, sliding gate valve positioned above the upper chute and includes a pair of inter-acting valve plates rollably supported by rollers. A pair of hydraulic cylinders are capable of moving the valve plates into partially overlapping relation for effective sealing of the flow path.  A lower chute defines a lower flow path and is capable of pivoting movement from a horizontal stored position to a position wherein upper and lower flow paths align for discharging material.  The lower chute is mounted by means of a triangular skirt pivotally secured to an overhead structure.  The triangular skirt includes an arcuate bottom plate enabling the lower chute to cover the upper chute discharge opening when the lower chute is being pivoted out of full alignment, thereby preventing material spillage from the upper chute.  A corresponding curved retainer plate is operative to cover the lower chute inlet opening during pivoting movement for preventing spillage.  A curved blade gate valve is positioned at the bottom portion of the lower chute operated by hydraulic cylinders carried outside the chute; the blade being operative to enter the lower flow path through a slotted opening in the chute, for incrementally opening and closing the lower flow path.  By positioning the curved blade gate valve in proximity to the bottom discharge opening of the lower chute, precise topping off at the end of the loading cycle may be achieved and material spillage is minimized.  Rapid pivoting movement of the lower chute is achieved with a power cylinder interconnected to the chute with a cable and pulley arrangement.  A power winch is also interconnected with the chute by the cable means and is capable of incrementally adjusting the lower flow path to ensure proper alignment with the upper flow path.
